Embodiment Construction

[0013] As shown in Figure 1,

[0014] The oil pipeline anti-theft oil detection method is that the light-emitting module of the optical transceiver 1 arranged at the source end of the oil pipeline sends out an optical signal, and the optical signal enters the optical fiber 4 in the optical cable 2 coated on the oil pipeline 5, and then transmits to the light signal installed on the optical signal. Relay amplification is carried out in the amplification device 3, and the amplified optical signal enters the optical fiber 4 in the optical cable 2 outside the oil pipeline 5 and is finally transmitted to the light receiving module of the optical transceiver 1 arranged at the oil pipeline terminal. Among them, the optical transceiver 1 and the optical signal amplifying device 3 both adopt the MATER1000 optical transceiver produced by Huawei.

[0015] The optical cable ribbon 2 is made up of 400 mm wide rubber band engraved with 10 longitudinal grooves and 10 optical fibers 4 embedde...

Abstract

The invention relates to oil delivery pipe oil theft-proof detecting method. Its features are that the source end of the oil delivery pipe is set light receiver and transmitter; its terminal also is the same; the luminescence module of the former transmits light signal to the light receiver of the latter by cable; according to the received light signal, it can judge whether the cable is damaged or not, further judge whether the oil delivery pipe exists oil thieving or not; if it is, it can use OTDR machine to detect cable break position. The method has high detecting sensitivity and exact locating. It is not easy to be explained by thieve. And it also can be used in gas delivery pipe monitoring.

Description

technical field [0001] The invention relates to the technical field of oil pipeline anti-theft oil, in particular to a detection method for oil pipeline anti-theft oil. Background technique [0002] At present, my country's oil and gas pipelines are quite common, but the phenomenon of oil and gas being stolen due to stolen oil and gas pipelines occurs from time to time, resulting in huge losses of national property. The oil and gas theft caused by the stolen drilling of gas pipelines, and the resulting maintenance costs are over 100 million yuan. The current anti-theft measure is manual inspection. However, because the oil and gas pipelines are long and buried underground, thieves often use the method of digging tunnels to drill holes on the oil and gas pipelines to steal oil and gas. Therefore, it is sometimes difficult to find out only by manually inspecting from the air and the ground, and the thieves have been committing crimes for several years when some cases are solv...
